. and useful Improvements in Spring-l/Vheels,

therethrough.

of whiclithe following is a specification.

The present invention relates tol spring Wheels andv it is the dominant Object of the invention to provide a wheel havingacush-` ion tire, whereby the same will fully absorb such shock as may be imparted; thereto during operation. i

n Another object of the invention is to provide asegmental tire for the wheel in order that the flexing of. the same, at the directl -ject through the radial openings formed in point of strain will be permitted.Y

Among other aims and objects ofthe in@ vention maybe recited the provisionof a wheel of the character mentioned with a Vview to compactness, Vand in which theiium-v ber ofparts are few, the construction simple,

the cost of production small, and efficiency Y and Operation high. a'

The improvements in the details and ar- .v

disclosed for the purpose of imparting a' full Y understanding of the same. In the drawings:

Figure lois aside elevation ofmy Vim-V proved spring wheel; and

" Figi)J is a Vfragmentary transverse section Similar characters of reference-.fare employed in all` of the above described views to indicate corresponding parts.

Referring now more specifically to the A'several figures of the said drawings, there is providedthe ordinary wheel, including a hub,f radiating spokesY and rim, designated in its entirety by the numeral 1 and having arranged upon the peripheral surface thereof a rim band 2 in which there is formed at suitable intervals-a plurality of radially disposedV screw threaded openings desigfrom'the screw threaded openings 3 inthev nated 3. Other openings extend radially rim `band 2', for a purpose which will be subseouiently apparent.

An outer rime is provided and comprises a plurality of segments, the adjacent edgesv of which are soarranged asfto permit inde- A V `cured to the opposite eXtremitiesof each of the segments of the outer rim 4t, by passing rivets .7 or other suitable fastening devices through said' apertured lugsv into engage- Y ment withthe various segments. Radially disposedV guiderods 8 are rigidly seated within the bottoms of the cups 5 and ypro- I the rim `of the wheel l, screw threads being arranged upon their inner extremity whereby locking nuts 9 may be turned into engagement therewith for an `Obvious purpose. n tionsthereof'screw threaded are turned into engagement with Vthe screw threaded Open-l ings 3 formed in the rim band 2 and when Other cups l0 having the base porv so vpositioned telescope within the alined cups 5.

Expansible coiled springs ll areA arranged within the telescoping cups 5 and 10 and are Vpreferably received about the guide rods 8, thus serving as means yfor yieldably maintaining the segments of the outer rim 4 in their normal positions.

From the foregoing, it will be'aplpreciated by rworkers in the art, that I have provided an exceedingly simple and eiiicient' spring wheel, and one which will fully absorb such ln a'spring wheel, an inner rim having a plurality of spaced apart radially disposed openings formed therein, a band arranged about the inner rim, said band being proshook as may be transmitted thereto during vided With a plurality of screw threaded pockets alned with the radially disposed openings, cupe having aperturedbottomS turnedfintq engagement with, .said Screw threaded pockets, a segmental outer rim,

cups and extendingthrough the apertnred" 10V bottoms of the firsty cups and the' adjacent radial openings inthe innerfrini, and coiled springs arranged `:in Vsajrlj telesccpcallyfengaged cups.
